Wiha 79256 Hex Drive Bit Set 8 Piece Metric

Product Description

The WIHA 79256 is an 8-piece hex drive bit set designed for use with 0.25-inch drive tools. Each bit is manufactured from steel with a chrome-plated finish and is insulated for added safety in electrical service environments. The set covers a full range of metric hex sizes from 1.5 mm through 8.0 mm, making it a practical tool for HVAC technicians, electricians, and plumbers who regularly work with metric fasteners on equipment panels, motor mounts, and access covers. The chrome-plated finish resists corrosion, and the insulated construction adds a layer of protection when working near energized components.

This bit set suits residential and light commercial service work where metric hex fasteners are common. It is well suited for equipment cabinet assembly, motor and fan bracket fastening, and general service tasks that require a range of metric hex sizes. Technicians working on imported HVAC equipment, control panels, or plumbing fixtures with metric hardware will find the full size range covers the most frequently encountered fastener sizes in the field.

Installation Notes

These bits are installed and removed by hand into any compatible 0.25-inch drive holder or power tool bit chuck. Always de-energize equipment before accessing fasteners on electrical panels or control enclosures, even when using insulated bits. Verify the correct metric size before applying torque to avoid fastener damage. Store bits in a dry location to maintain the chrome-plated finish.
